1. I talk with students about why manipulatives help them learn math. These discussions are essential for first-time users and useful refreshers to refocus from time to time. I precede discussions by giving children time to explore a manipulative. Then we talk about what students noticed and I introduce the concepts they'll learn with the material.

2 .From day one, I set ground rules for using materials. We talk about the similarities and differences between using manipulatives in class and playing with toys or games. With toys or games, children can make up their own rules. With manipulatives, they are given specific problems and activities. I do make clear, however, that they're free to make discoveries and explore new ideas. It's also important for students not to interfere with one another. I step in when I hear a howl of protest as a student who needs one more yellow tile takes it from another group's table. Sometimes I open up the discussion to the entire class. These impromptu reminders help keep students on track.

3. I set up a system for storing materials and familiarize students with it. It's important for students to know where and how to store materials. A clear system makes the materials more accessible. Some teachers designate and label space on bookshelves. Others use zip-top plastic bags and portion materials into quantities useful for pairs or groups. Still others place a supply of each material at students' tables so they're always within reach. 4. Time for free exploration is worth the investment. Whenever I introduce a new material, I allot at least one math period for this. Teacher demonstrations alone are like eating a papaya in front of the class and expecting children to know how it tastes. 2Free exploration time also allows students to satisfy their curiosity so they don't become distracted from the assigned tasks. Expect children to see if tiles can fall like dominoes;...

QUESTION 1
DESCRIBE CHARACTHERISTICS OF (a) AN ALLOY (b) PEARLITE (c) AUSTENITE (d) MARTENSITE (e) CEMENTITE (f) SPHERODITE AND (g) TEMPERED MARTENSITE.
(a)ALLOY
• Alloy steel is often subdivided into two groups: high alloy steels and low alloy steels. The difference between the two is defined somewhat arbitrarily. However, most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel. Low alloy steels are slightly more common. The physical properties of these steels are modified by the other elements, to give them greater hardness, durability, corrosion resistance, or toughness as compared to carbon steel. To achieve such properties, these alloys often require heat treatment..Example of an alloy
 Alloy of aluminium:
Duralumin,nambe,silumin
 Alloy of cobalt:
Megallium,alnico,vitallium
 Alloy of copper:
billon,brass,berryllium copper,bronze.
Charactheristics of an alloy:
Hardenability : the capability of the alloy to be hardened through heat treatment
Hardness/strength : the capability to resist pressure, force or other stress
Heat resistance : the capability to resist heat
Thermal conductivity :...

...toward representatives of the church throughout the Inferno.
Among the Simoniacs Dante meets Nicholas III who mistakes Dante for his future successor in hell Boniface VIII. Dante uses this encounter to damn not only Boniface VIII but Clement V as well to the malebolge reserved for simony for their violation of everything the Catholic Church stands for. Mind you Pope Clement V and Boniface VIII where still alive when he did this. The significance here is that Dante specifically reserved a spot in hell for all those who violate clerical power and a warning to all those who will go into these offices in the future. Boniface VIII although not in the Inferno himself has already been damned for simony, “the selling of spiritual benefits for material gain.” (Burge) Boniface is frequently mentioned as the one who corrupted the church and, “crossed the line between spiritual and temporal powers.” Dante uses many invectives to shun Boniface and at one point even “enlist St. Peter himself to state equivocally ‘that he is responsible for turning the papacy into a sewer.” (Burge) Dante firmly believed that the imperial authority came from God “and was no way associated with the pope” (D.P.) Dante would often refer to the Church as a whore because of how it would sell indulgences and favors the highest bidder, and most of that was due to the Pope. So most of the time he is assaulting the Catholic Church he is referring to the Catholic Churches short coming. For example...

BRIEF INTRODUCTION: Beetroot cells contain a red pigment stored in the cell vacuole in the membrane to prevent leaking out from the cell. In this experiment we used several solvents to calculate which one made the cell release more pigment.
RESULTS: A table showing the results of the intensity of the color and the absorbance of the liquids with the different solvents.
Solvent
Results from colorimeter 0.001
Acid (Hydrochloric)
0.358
Ethanol
0.132
Hot water
0.984
Cold water-distilled water (control)
0.057
CONLUSION: The results show that hot water gave the highest average absorbance reading from the colorimeter, followed by hydrochloric acid, ethanol and cold water, in descending order of absorbance.
The absorbance of the solvent that was hot water affected the most the permeability of the cell membranes. This is because if the temperature is higher it will break down big part of the membrane due to the fact that when heat energy is given to something, the electrons will vibrate therefore breaking their bonds and changing state of matter, with hot water the membrane from the beetroot released more pigment fitting this process. We kept temperature of the hot water constant and we did not let it boil because this could affect the pigment released by the beetroot, it could potentially denature the membrane of the beetroot.
Hydrochloric acid in other words, the pH can affect the membrane affecting the proteins that make up cell membranes therefore...

Abstract
With the development of science, people start to decrease occurrence of death, for example, people investigated some useful therapy to treat people’s disease in pharmacology. Also, human want to figure out the natural disaster like tsunamis and volcanic eruption to let people are longevity. Although today’s technic are not enough to solve those disasters, people can use the different instrumentality to forecaster. In addition, people always prefer compare and contrast these instrumentalities to develop what they’ve already discovered. Thus, I’d love to discussed the advanced technology artifice of what I’ve just mentioned as examples— eruption of tsunamis and volcanic which reflect on millions of economic losing and death.
Introduction
Here’s an adage of ancient China called Man Proposes, God disposes, which can be translated as human’s power are very chickenshit in front of nature. People cannot decide when and where the disaster happened, they even cannot stop them, but with the...

1. Problem #1, page 15 in textbook.
Imperfect competition structure market is the market where there are very few companies, so that they have the power control the market. Because tehre are very few competitors, they can charge their products or services more than the market value. It means that they can decide the price for their products and services.
Some examples are electric market, water supply market, and fuel market in Vietnam. Because there is only one electric company and very few company in water supply market and fuel market, so that they can decide their price and charge a high price for their service. The reason is the government regulations in Vietnam, the government controls those market.
2. Problem #2, page 15 in textbook.
The perfectly competitive market does not reflect a setting of strategic interaction because in this market structure each firm can not decide the price for their product or service. As the result, they do not need to make plan or strategy for their firms.

a. A fruit doesn’t necessarily have to be edible. Generally, it is just a ripened ovary that usually contains multiple seeds. By this definition, wisteria pods are indeed, fruits. Other fruits include berries, strawberries, and the other mainstream fruit most often consumed by humans. A fruit does not have to be fleshy or dry, sweet or soft. Eiseley realized that seeds were travelers, making the fruit a form of transportation. He found that they came in many forms, including those that are winged, hooked, or spiked. The common fruit eaten by humans has seeds that pass through the body undigested and come out in a new place.
11. What is the advantage of insect pollination over wind pollination?
a. It allows the spread of genetic material from plants over a wide area. Wind-pollinated plants cannot achieve the same reach. The simple flower sent and received pollen solely by wind. Flowers with pollen attractive to insects allowed pollen to spread even more easily and even further.
12. What are the three sources of food that come from flowering plants? How did these affect the success of warm-blooded animals that have high metabolism?
a. The three sources of food were the following: nectars and pollens intended to draw insects to pollinate the plants, fruits to attract larger animals, and food inside the actual seed to feed the embryo when needed. At the beginning of the age of flowers, a global climate change resulted in the vanishing of most...
